Nonionic polyacrylamide (NPAM)
Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water to bridge the particles or aggregate the particles to form large flocs through charge neutralization. Therefore, it can accelerate the sedimentation of particles in suspension, and has very obvious effects on accelerating solution clarification and promoting filtration. Mainly used for flocculation, sedimentation and sedimentation clarification of various industrial wastewaters. Such as papermaking and pulp wastewater treatment, wastewater treatment in mineral processing and metal smelting processes, wastewater treatment in steel plants and stone processing plants, etc.
Nonionic polyacrylamide product features:
Since nonionic polyacrylamide (NPAM) is a high-molecular polymer or polyelectrolyte, its molecular chain contains a certain amount of polar genes that can adsorb solid particles suspended in water, forming bridges between particles to form large flocs. It accelerates the sedimentation of particles in suspension, has a very obvious effect of accelerating the clarification of the solution and promoting filtration. It is widely used in the treatment of chemical industry wastewater and waste liquid, and municipal sewage treatment. Especially when the sewage is acidic, this product is suitable. It can be used in conjunction with inorganic flocculants such as polyiron, polyaluminum and other inorganic salts.
Packaging and storage of nonionic polyacrylamide:
This product is a non-toxic powdery granular product that is easily affected by air, thus affecting its quality. Therefore, it should not be stored in a humid or sunny environment. In addition, during loading, unloading and transportation, it is necessary to avoid contact between PAM and iron and copper metals. Diaphragm pumps and piston pumps are preferred for delivery pumps. The storage period of solid granular or powdered polyacrylamide is 2 years.
